Factor of safety for sliding

WebPipe angle from horizontal = 45 0. Horizontal force = PA (1-cosθ) = 600 x π x 1.2 2 (1-cos45)/4 = 200 kN. The horizontal force is in the direction of the pipe. Vertical reaction = PA sinθ = 600 x π x 1.2 2 x (sin45)/4 = 480 kN. … WebA further factor of safety which is sometimes used is F H, the factor of safety with respect to height. This is defined as the ratio between the maximum height of a slope to the actual height of a slope and may be expressed as follows: FH = Hmax H (11.5) The factors of safety F c, F φ, F H are only occasionally used in slope stability analyses.
